Description
Technical Field
[0001] The utility model relates to the technical field of electron irradiation chambers, in particular to an isolation device for a material electron irradiation chamber. Background Art
[0002] An electron irradiation room is a special environment used for conducting electron radiation experiments or tests. This environment usually requires special equipment and facilities to control and monitor the dose and distribution of electron radiation. In an electron irradiation room, radiation effect tests of various electronic devices, materials and systems can be performed, such as evaluating the performance and reliability of electronic equipment in a radiation environment. These tests can help engineers understand the performance of equipment in a radiation environment and take appropriate measures to improve the radiation resistance of the equipment. Electron irradiation rooms usually require special shielding and protection measures to ensure the safety of experimenters and the accuracy of experimental results. At the same time, electron irradiation rooms also need to be equipped with professional equipment and instruments, such as radiation dosimeters, electronic loads, signal generators, etc., for accurate testing and measurement.
[0003] The existing technology requires that the product be transported to the bottom of the electron accelerator through a channel by a transport device in the irradiation room and then the product is irradiated. Since the transport device needs to enter and exit the channel during the irradiation process, the isolation door at the traditional channel entrance needs to be opened frequently to allow the transport device to transport the product. However, this situation is very dangerous. In this case, the staff are extremely susceptible to the hazards of radiation and damage to their health. Therefore, we need to propose an isolation device for the material electron irradiation room. Utility Model Content
